DRAINAGE AND SEWERAGE
A further length of the old main soil sewer was reconstructed
during the year, involving approximately 470 yards southwards
from Magpie Hall Lane.
Cesspools.
No new houses were erected with cesspool drainage during
1955.
Eighteen individual cesspools were emptied by the Borough
Engineer's Department upon the request of the householders.
RIVERS, STREAMS AND LAKES.
The piping of a length of 185 yards of the river Ravensbourne
immediately north of Hayes Lane was completed.
A contract was let for further culverting of the river at the
rear of houses in Newbury Road and immediately north as far as
Glassmill Lane. This work was commenced and substantial progress
made on the site. The scheme includes the construction of a
storage lake on the site of the former mill pond at the rear of the
houses in Mill Vale, and the lowering of the invert of the existing
culvert under the railway line near Newbury Road.
SWIMMING BATHS AND POOLS.
The Sanitary Inspectors made a total of 279 visits of inspection
to Swimming Baths and Pools in the Borough and forty samples of
water were taken for examination.
